Method for producing hydroxyphenyl acrylate monomers and polymers

New syntheses of phenolic acrylate monomers are provided as well as polymers comprising such phenolic acrylate monomers. Preferred polymers of the invention are useful as a resin component of chemically-amplified positive-acting resists.

Thermal dimerization of alkali and alkaline earth acrylate-but-3-enoate and methacrylate-but-3-enoate binary systems in the solid state

The solid state thermal reaction of binary salts obtained from a solution of an equimolar mixture of alkali or alkaline earth salts of but-3-enoic acid and methacrylic acid (3-BA-MA), after conversion to the methyl ester, gave mainly dimethyl (E)-hex-1-ene-1,5-dicarboxylate as a novel cross-coupled dimer. The highest conversion (62.2%) to the cross-coupled dimer was obtained using the potassium salts on heating at 230°C for 2 h. Similarly, the methyl ester of the cross-coupled dimer, dimethyl (E)-pent-1-ene-1,5-dicarboxylate, was obtained from the salts of 3-BA and acrylic acid (AA), however a small amount on an isomeric ester dimethyl (E)-pent-2-ene-1,5-dicarboxylate was also obtained. The X-ray diffraction patterns of potassium 3-BA-MA and potassium 3-BA-AA indicate the presence of a new phase, different from that of the individual salts. The selective cross-coupled dimerization, without rearrangement of 3-BA to crotonic acid, polymerization and crosslinking, was due to the new crystal phase of the binary salts as well as to the formation of solid solution crystals between the monomeric salts and the dimeric salt.

Thermal Cross-coupled Dimerisation of Alkali and Alkaline Earth Metal Salts of Methacrylic-Crotonic Acid Binary Systems in the Solid State

Thermal reaction of sodium and potassium salts of methacrylic-crotonic acids in the solid state selectively affords a cross-coupled dimer, dimethyl hex-1-ene-2,4-dicarboxylate.

HIGH-TEMPERATURE HYDRATION OF ACRYLIC AND METHACRYLIC ACIDS

In the high-temperature liquid-phase reaction of acrylic and methacrylic acids with water the directions of hydration differ; β-hydroxypropionic and α-hydroxyisobutyric acids respectively are formed, and this agrees with an electrophilic mechanism of hydration.A method is proposed for the production of β-hydroxypropionic acid by hydration of acrylic acid.It was found that competing reactions leading to the formation of oligomers occur during the hydration of methacrylic acid.
